Patent number: 11049144Abstract: Disclosed herein are methods and systems for combining, in real time, images of one or more real life objects that have been captured in real time based on a comprehensive characteristic-based mechanism with a virtual environment to provide an augmented reality environment to a user or user device. In particular, the captured images are provided to a remote server that is capable of performing the processing steps to create a plurality of integrated images. The plurality of integrated images can then be provided to the user device. Advantageously, the remote server can create the plurality of integrated images much more quickly due to the server's enhanced computing power and storage space as compared to the user device. The remote server may be an intermediate server between multiple user devices. The comprehensive content matching mechanism is based on a plurality of factors comprising advertisement content, user preference information, and context information.Type: GrantFiled: December 18, 2019Date of Patent: June 29, 2021Inventor: Eliza Yingzi Du

Patent number: 10146929Abstract: Techniques described here use variations in the sensor to generate an identifier for the sensor. Each sensor may be comprised of sub-sensing units, called pixels that may demonstrate variation in their sensing capability from one pixel to another. Embodiments of the invention, describe a method for using the relative variance of each pixel (relative to the whole sensor or/and a portion of the sensor) in generating an identifier for the sensor. In one embodiment, the method may obtain information associated with a plurality of pixels from a sensor, detect variations in the information associated for each of the pixels from a subset of the plurality of pixels and generate an identifier for the sensor using the detected variations in the information associated with each of the pixels from the subset of plurality of pixels.Type: GrantFiled: November 17, 2015Date of Patent: December 4, 2018Assignee: QUALCOMM IncorporatedInventors: Eliza Yingzi Du, John Keith Schneider, Suryaprakash Ganti

Patent number: 9953233Abstract: A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.Type: GrantFiled: March 28, 2017Date of Patent: April 24, 2018Assignee: QUALCOMM IncorporatedInventors: Eliza Yingzi Du, Ming Yu Chen, Esra Vural, Kwokleung Chan, David William Burns, Suryaprakash Ganti, John Keith Schneider, Saurav Bandyopadhyay, Jin Gu
